I got the ceramic insulator from Switchblade to make it easier to use I have added a handle to it yes its just a branch and I used construction adhesive I pumped it into the center void and pushed the branch in hay it works great I have just finished sharpening all the kitchen knifes have to say it works slick..
Switchblade was saying that they used these ceramic insulators in very old homes it was when they needed to go through wood beams and then they would put the insulator through the hole then the wiring through the insulator just to make sure that for whatever reason the wiring does not catch the wood on fire when the electrical gets over loaded….
Since using it as a knife sharpener not its intended purpose it is not perfect and had a couple of imperfections on the surface but It was easy to fix by just using a sharpening stone and going over the imperfections its now a nice smooth surface to sharpen my knifes…
